* with a \c NULL parameter.
* - The \ref Serial_ReceiveByte() function has changed, and now returns a signed 16-bit integer, with -1 indicating no data was
* received.
+ * - The TWI driver \ref TWI_Init() function now expects additional prescaler and bitlength parameters. See the function
+ * documentation for more details.
+ * - The name postfix on all driver modules to turn off and disable that module has been changed from *_ShutDown() to *_Disable().
+ * Rename all references to these functions to use the new function names.

* <b>USB Core</b>
* - By default, unordered Endpoint and Pipe configuration is now allowed once again, via the previous workaround of
* reconfiguring all Endpoints/Pipes in order each time a new Endpoint/Pipe is created. To minimise the compiled program
* size, the new \c ORDERED_EP_CONFIG compile time option may be defined in the project makefile to restrict the ordering
* in exchange for a smaller compiled binary size.
+ * - The previous F_CLOCK symbol, required in the project makefile, has been renamed to F_USB. This is due to the previous name
+ * being far too generic for use in future architecture ports, where multiple clock domains are used.
*
* <b>Device Mode</b>
* - The Endpoint stream functions now all require a \c BytesProcessed parameter instead of the previous callback parameter.
* error code to allow the user application to determine when to send the next chunk of data.
* - The \ref CDC_Device_SendString() function now expects a null terminated string instead of an explicit length. Existing code
* should use the new \ref CDC_Device_SendData() function, or remove the length parameter from the function call.
+ * - The Endpoint_ResetFIFO() function has been renamed to \ref Endpoint_ResetEndpoint(), to make the API function names more
+ * consistent. Existing applications using the old function name should simply replace it with a call to the new function name.
+ * - The Endpoint_*_Byte() functions have been renamed Endpoint_*_8() to ensure they are correct across all architectures. Existing
+ * code using these functions should replace the previous function names with the new function names.
+ * - The Endpoint_*_Word() functions have been renamed Endpoint_*_16() to ensure they are correct across all architectures. Existing
+ * code using these functions should replace the previous function names with the new function names.
+ * - The Endpoint_*_DWord() functions have been renamed Endpoint_*_32() to ensure they are correct across all architectures. Existing
+ * code using these functions should replace the previous function names with the new function names.
*
* <b>Host Mode</b>
* - The Pipe stream functions now all require a \c BytesProcessed parameter instead of the previous callback parameter.
* - The \ref PRNT_Host_SendString() and \ref CDC_Host_SendString() functions now expect a null terminated string instead of an explicit
* length. Existing code should use the new \ref PRNT_Host_SendData() and \ref CDC_Host_SendData() functions, or remove the
* length parameter from the function call.
+ * - The Pipe_ClearErrorFlags() function has been removed, as the pipe error flags are now automatically cleared when the
+ * \ref Pipe_ClearError() function is called.
+ * - The Pipe_*_Byte() functions have been renamed Pipe_*_8() to ensure they are correct across all architectures. Existing code using
+ * these functions should replace the previous function names with the new function names.
+ * - The Pipe_*_Word() functions have been renamed Pipe_*_16() to ensure they are correct across all architectures. Existing code using
+ * these functions should replace the previous function names with the new function names.
+ * - The Pipe_*_DWord() functions have been renamed Pipe_*_32() to ensure they are correct across all architectures. Existing code using
+ * these functions should replace the previous function names with the new function names.

* the \ref SPI_Init() function documentation for more details

* - The \c Host_IsResetBusDone() macro has been renamed to \c Host_IsBusResetComplete().
